Abstract
The invention provides a method for preparing a liquid rubber special for nipple and the liquid rubber special for nipple. The preparation method comprises the following steps: 1, adding vinyl silicone oil, fumed silica, hexamethyl-disilazane and a small amount of dimethyldiethoxysilane, a coupling agent and water into a cooling kneading machine, and kneading the mixture; 2, closing a cooling system, and heating the kneaded mixture to 150 DEG C and cooking for 2 h; 3, vacuumizing for 1 h under a degree of vacuum higher than 0.098 MPa; 4, slowly adding ethylene silicone oil under the protection of nitrogen; and 5, cooling to lower than 60 DEG C and discharging to obtain a base rubber for liquid nipple rubber.
Description
Technical field
The present invention relates to baby nipple manufacturing technology field, particularly relate to liquid glue of a kind of nipple special use and preparation method thereof.
Background technology
The liquid nipple glue of vapor phase process is when being prepared into nipple at present, and the transparency of nipple is not high, is difficult to satisfy the market requirement more and more higher to the baby nipple transparency.Produce in addition that to occur the nipple physicals easily in the process of nipple not enough, when making the finished product delivery, be torn defect ware rate height easily.
In the existing technology, often take hexamethyldisilazane as being the structurizing treatment agent, strengthen cohesiveness.Generally take at present then after vacuumizing 2 hours under a certain fixed temperature, liquid nipple gum is made in the adding vinyl silicone oil dilution of uncapping, this treatment process removes not exclusively the low molecule that remains in the sizing material, cause the sizing material transparency not enough, when making the nipple goods, easily produce atomizating phenomenon.
Summary of the invention
Based on this, the invention provides liquid glue of a kind of nipple special use with good transparency and demolding performace and preparation method thereof.
A kind of preparation method of liquid glue of nipple special use, this preparation method may further comprise the steps: the first step, in the kneader of cooling, add vinyl silicone oil, thermal silica, hexamethyldisilazane and a spot of dimethyldiethoxysilane, coupling agent and water, mediate these mixtures agglomerating; Second step, close cooling system, the mixture after this kneading was warming up to 150 degree heat refinings 2 hours; In the 3rd step,, vacuumized 1 hour greater than under-the 0.098MPa in vacuum tightness; In the 4th step, under nitrogen protection, slowly add vinyl silicone oil; The 5th step was cooled to 60 degree with bottom discharge, got liquid nipple matrix glue.
Further, the described the first step and the vinyl silicone oil in the 4th step are two end-blocking vinyl silicone oils.
Further, the viscosity of the two end-blocking vinyl silicone oils in the described the first step is 45000mpa.s, and the viscosity of the two end-blocking vinyl silicone oils in described the 4th step is 30000mpa.s.
Further, the specific surface area of described thermal silica is 400.
Further, the mass percent of the vinyl silicone oil in the described the first step, thermal silica, hexamethyldisilazane, dimethyldiethoxysilane, coupling agent, water and the vinyl silicone oil in the 4th step is respectively 30.3%, 22.1%, 4.3%, 1.1%, 0.4%, 1.4%, 40.4%.
A kind of liquid glue of nipple special use, the liquid glue of this nipple special use is made by the material of following mass percent: 30.3% viscosity be two end-blocking vinyl silicone oils, 22.1% the specific surface area of 45000mpa.s be 400 thermal silica, 4.3% hexamethyldisilazane, 1.1% dimethyldiethoxysilane, 0.4% coupling agent, 1.4% water, and 40.4% viscosity be two end-blocking vinyl silicone oils of 30000mpa.s.
Embodiment
The main raw material of the liquid glue of nipple special use of the present invention comprises vinyl silicone oil, thermal silica, hexamethyldisilazane, and a spot of dimethyldiethoxysilane, coupling agent and water.The preparation method of the liquid glue of nipple special use of the present invention is: the first step, in the kneader of cooling, add vinyl silicone oil, thermal silica, hexamethyldisilazane and a spot of dimethyldiethoxysilane, coupling agent and water, mediate these mixtures agglomerating; Second step, close cooling system, the mixture after this kneading was warming up to 150 degree heat refinings 2 hours; In the 3rd step,, vacuumized 1 hour greater than under-the 0.098MPa in vacuum tightness; In the 4th step, under nitrogen protection, slowly add vinyl silicone oil; The 5th step was cooled to 60 degree with bottom discharge, got liquid nipple matrix glue.Wherein, this coupling agent can adopt phosphoric acid ester or other coupling agent.
The liquid glue sizing material of the nipple special use of this method preparation is transparent, can not produce atomizating phenomenon when making the nipple goods, and the easily demoulding, and vulcanization rate is fast, can improve the impart tear of product, and improves the stability of product.
Among the concrete embodiment, the preparation method of the liquid glue of nipple special use of the present invention is: the first step, mass percent is that 30.3% viscosity is two end-blocking vinyl silicone oils of 45000mpa.s, mass percent is that 22.1% specific surface area is 400 thermal silica, mass percent is 4.3% hexamethyldisilazane, mass percent is 1.1% dimethyldiethoxysilane, mass percent is 0.4% coupling agent, and mass percent is that 1.4% water mixes in the kneader of cooling (temperature is lower than 10 degrees centigrade), and these mixtures kneadings are agglomerating; Second step, close cooling system, the mixture after this kneading was warming up to 150 degree heat refinings 2 hours; In the 3rd step,, vacuumized 1 hour greater than under-the 0.098MPa in vacuum tightness; In the 4th step, slowly adding mass percent and be 40.4% viscosity under nitrogen protection is two end-blocking vinyl silicone oils of 30000mpa.s; The 5th step was cooled to 60 degrees centigrade with bottom discharge, got liquid nipple matrix glue.
